Dog Bark Deterrent Device (Anti Barking Device)

I bought 2 of these & came with zero instructions & dont make an ounce of difference as my dog obviously can’t hear the supposed noise these are supposed to make, complete waste of time & money. If your thinking of getting one please dont waste your time & money.

Instructions were not helpful. Customer service was very responsive but after several emails back and forth, they still could not provide clear instructions. I do not believe customer service even knows how to operate the product. As such, I cannot get the full benefit because I cannot make adjustments as needed.

It doesn’t stop my dog from barking if fact he barks at it more. Total waste of money again
